CLEAT CHAIN CONVEYERS.

Specification of Letters Patent. Patented Apr. 9, 1918 Application filedAugust 18, 1917. Serial No. 186,953. v

To all whom it may concern:

Be it known that I, JACKSON H. CLARK, a citizen of the United States,residing at Sunburst, in the county of Haywood and State of NorthCarolina, have invented new and the object of the invention being toprovide a. cleat which is light,strong and durable, simple ofconstruction and comparatively inexpensive of production, and which iscomposed of sections adapted to be easily assembled and firmly securedto a chain link and to present a broad abutment surface for engagementwith the slab or other object.

"With this and other objects in view, the invention consists of thefeatures of construction, combination and arrangement of parts,hereinafter fully described and claimed, reference being had to theaccompanying drawing, in which Figure 1 is a rear perspective viewv of acleat embodying my invention as applied to a link of a conveyer chain.

Fig. 2 is a front elevation of the same.

Fig. 3 is a vertical longitudinal section through the applied cleat.

Figs. 4 and 5 are vertical transverse sec- 7 1 tions.

Fig. 6 is a view showing the sections of the cleat disassembled anddisposed to expose the construction thereof.

In the practical embodiment of my inven- V pending to a degree equal tothe thickness tion I provide a cleat comprising a pair of outer cleatsections 1 and 2 and an intermediate or central cleat section 3. Thesecleat sections are united in the manner hereinafter described to en ageone of the links 4 of a conveyer chain, the cleat being extended throughthe link and in engagement.

therewith at its center, and projecting to equal degrees beyond oppositesides of the link. For convenience of description the outer cleatsection 1 may be termed the top cleat section, and the outer cleatsection 2 the bottom cleat section.

The cleat sections are preferably of: the

form shown, each comprising a metallic plate having a straightlongitudinal front edge, and having its rear edge inclined on diverginglines from the center of the cleat toward the ends thereof, the cleatthus being made of maximum width at the center, but this form of cleatis not absolutely essential and may be departed from if desired. Inpractice, the cleats may be arranged any desired distance apart alongthe conveyer chain, and each cleat engages a vertically disposed link ofthe chain, as shown.

The top and bottom cleat sections 1 and 2 are alike in construction, andhence a description of one will suflice for both. As shown, the cleatsection 1' is provided in its outer face with a transversecentral groove5 which receives and engages one of the sides of the linkl, while theinner or reverse face of said cleat section is formed with'a'rib or boss6, Which thickens and increases the depth of the cleat section in thevertical plane of the groove and plane of engagement of the cleat withthe chain link, to increase the strength and durability of the cleat atthe center, to adapt it to effectually withstand the pressures andstrains falling thereon. The inner face of the cleat section 1 isfurther provided with lugs 7 arranged adjacent to and on opposite sidesof the boss 6, and lugs 8 arranged adj acent t0 the ends of said cleatsection, the said cleat section being formed with openings 9 and 10respectively passing through the inner and outer sets of lugs. The lugs7 and 8 correspond in depth or other object which is to be transported.

termediate cleat section differs from the top antl'lsOtiZOHItClGEtiFSGGblOIIS in that it; is -devoicl of the groove 5, itslower, facebeingfiator plane-surfaced throughout.

By the constructionofthecleat sections in; the manner described, a/form, of

cleat is produced I which, while exceedingly strong and'durabl is lightin weiglitand much less expensive thanv a. construction, employingsolid. cleat blocks on sections.

In. applying the, cleat. to the. chain' link the bottom cleat. section2.is firstinsertedlin position.- through; the link, after which the topcleat section is arranged in pl,21(2e 2 11 1l then. the intermediatecleat. section is inserted fromione endbetweenthe top fillClQljOll' tomcleat. sections, thus spreading the same apart. and binding them. intoengagement with the, Side barsof'the links which are receivediintoithegrooves 5, the rivets or bolts sections.-v may. be, with. the,exeeptionof the groovesihflat on of: any other desired formation.

From the foregoing description, taken in connection with the drawing,the construction; and mode of. application and use of my improvedsectional cleat-will be readily understood, and it will be seen that acleat is provided which; is siinple of construction,

capable of being easily and conveniently applied for use and as easilyremoved for 1 repairs, the substitution of a new cleat-or cleatsectioiuori for other purposes. It will also be seentliatt-lieconstruction described is of material advantage fromthe standpoint of.economy and lightness in wei'gl'it, withoutsacrifice oif'strengtliandrdurability.
